JsonKey class - json_annotation library

Constructors

JsonKey({@Deprecated('Has no effect') bool? nullable, Object? defaultValue, bool? disallowNullValue, Function? fromJson, bool? ignore, bool? includeIfNull, String? name, Object? readValue(Map, String)?, bool? required, Function? toJson, Enum? unknownEnumValue}): Creates a new JsonKey instance.
const

defaultValue → Object?: The value to use if the source JSON does not contain this key or if the value is null.
final
disallowNullValue → bool?: If true, generated code will throw a DisallowedNullValueException if the corresponding key exists, but the value is null.
final
fromJson → Function?: A Function to use when decoding the associated JSON value to the annotated field.
final
hashCode → int: The hash code for this object.
read-onlyinherited
ignore → bool?: true if the generator should ignore this field completely.
final
includeIfNull → bool?: Whether the generator should include fields with null values in the serialized output.
final
name → String?: The key in a JSON map to use when reading and writing values corresponding to the annotated fields.
final
readValue → (Object? Function?(Map, String)?): Specialize how a value is read from the source JSON map.
final
required → bool?: When true, generated code for fromJson will verify that the source JSON map contains the associated key.
final
runtimeType → Type: A representation of the runtime type of the object.
read-onlyinherited
toJson → Function?: A Function to use when encoding the annotated field to JSON.
final
unknownEnumValue → Enum?: The value to use for an enum field when the value provided is not in the source enum.
final

noSuchMethod(Invocation invocation) → dynamic: Invoked when a non-existent method or property is accessed.
inherited
toString() → String: A string representation of this object.
inherited

nullForUndefinedEnumValue → const Enum: Sentinel value for use with unknownEnumValue.
